Invasive Species Programs• SFWMD’s objective is to manage invasivespecies of the WCAs and the ECB. Primaryobjectives include melaleuca, schinus andlygodium. The SFWMD program started withmelaleuca almost 20 years ago.• FWC shares these, with an emphasis on treeislands. Every year we contract exotictreatment, native tree and shrub planting, andmaintenance of planted trees on hundreds ofacres of tree islands.


Priority Animal Species• Priority Animals– Burmese and Northern African pythons– Purple swamphens (Porphyrio porphyrio)• Newly Detected Animal Species– Banded Caracol (Caracolus marginella) snail foundon WCA3B tree island this spring


Fiscal Year Treatments: 2010SFWMD (October- June)• Melaleuca– WCA2B– WCA3AN– East Coast Buffer– Pennsuco– Rotenberger WMA– Covered 52,900 acres– $993,000


Fiscal Year Treatments: 2010SFWMD (October- June)• Schinus– WCA3B islands– WCA3AN – deerislands– Levees– Covered 800 acres– $74,715


Fiscal Year Treatments: 2010SFWMD (October- June)Lygodium• WCA3b– Known locations onislands (not all islands)– Entire East CoastBuffer (beyond image)• Treated if found whentreating other species• Covered 2000 acres• $212,300


Planned Treatments: 2011SFWMD• Melaleuca(maintenance control)• WCA 2A (north)• WCA 2B (fire area)• WCA 3AN (north)• Lygodium• WCA 3B• WCA 3A


• Rotenberger WMA:103.7 acres = $24,981.333000 trees planted• Holey Land WMA:360.6 acres = $65,448.90• Everglades WMA:353 acres = $73,388.709,400 cages maintained =$70,622.20• Southern GladesExotic treatment andtree and shrub plantingFiscal Year Treatments: 2010FWC (July—June)

Monitoring• ECISMA-wide Digital Aerial Sketch-mapping(DASM)• Contract for tree island surveys, primarily forlygodium (not funded 2011)• Cattail surveys in Holey Land & Rotenberger WMAs• Tracking exotic treatment and other restorationactivities in ArcView and spreadsheets• Camera trapping to monitor wildlife utilization• Photopoints to monitor changes in vegetation overtime

Innovations and SuccessesPrescribed fire in WCA 2B3000 acres burned


Innovations and successes• Reptiles of Concernrecently reclassified asconditional species• Can no longer beacquired for personalpossession• Pet owners can surrendertheir conditional specieswith no penalty• More species to beevaluated and added toROC or conditionalspecies lists soon• Burmese python• Northern & SouthernAfrican python• Reticulated python• Amethystine python• Scrub python• Green anaconda• Nile monitor


Innovations and successes• Python permit program began in 2009 toallow qualified Floridians to takeROCs/conditional species• Hunters also allowed to take ROCS/conditionalspecies during hunting seasons on theseWMAs• Owners of former ROCs are grandfathered inbut must maintain ROC license and microchiptheir animals


Needs & Gaps• Identify critical needs and gaps– Additional survey of islands for lygodium– Herbicide info for treating lygodium when water ishigh– More research on water level impacts onlygodium expansion– More surveys of tree island elevation—also criticalto lygodium expansion
